Description

Technical Field

[0001] The utility model relates to an agricultural machine, namely a pepper fine screening and picking machine. Background Art

[0002] Large areas of pepper production areas need to adopt mechanical operations, especially the pepper harvesting process, which is time-sensitive and labor-intensive, and the demand for mechanization is particularly urgent. To this end, I have developed several pepper picking machines. The above-mentioned pepper picking machines are mostly composed of a feeder, a crushing bin, and a sifter, which can crush the pepper plants that have been cut and dried to separate the peppers from the stems. However, during the pepper crushing and screening process, the peppers will be damaged and the pepper seeds inside will be scattered. Since the picker is not equipped with a pepper seed collection component, the pepper seeds are screened out along with the crushed stems and lost. Studies have shown that pepper seeds are also important condiments, medicines, and industrial raw materials, and it is a pity to throw them away. Summary of the invention

[0003] The utility model aims to develop a pepper fine screening and picking machine which can not only harvest peppers but also collect scattered pepper seeds.

[0004] The above object is achieved by the following technical scheme: a chili fine screening and picking machine is provided, comprising a feeder, a crushing bin, and a sifter, wherein the sifter is cylindrical, the cylinder wall is surrounded by a plurality of slender slats, and there are sifting gaps between adjacent slats, and the feature is that: the cylindrical sifter is placed flat on the frame and supported by rollers on both sides of the frame, and the rollers on both sides can rotate, wherein the roller on one side is an active roller that rotates under the drive shaft, and the roller on the other side is a driven roller, and the active roller can drive the sifter to rotate when it rotates;

[0005] The front part of the sifter is provided with a seed sieve surrounded by a filament sieve, and the seed sieve is covered with sieve holes that can pass the pepper seeds;

[0006] A seed collecting box is arranged below the frame. The seed collecting box is surrounded by box walls and a box bottom. The upper opening of the seed collecting box is opposite to the seed sorting screen.

[0007] The cross section of the strip is rectangular or trapezoidal, and the short side of the trapezoid faces the inner side of the cylinder.

[0008] The cross section of the strip is triangular, with one of the sharp corners facing the inner side of the cylinder.

[0009] The seed collecting box is provided with a sieve at the bottom, the sieve holes of the sieve can retain the pepper seeds and screen out impurities smaller than the pepper seeds. The wall of the seed collecting box is movably connected to the frame, and a transmission shaft is provided on one side of the frame. The front end of the transmission shaft is transmitted to the power machine, and the transmission shaft drives a crank-connecting rod mechanism through a sprocket and is hinged to the wall of the seed collecting box. The seed collecting box oscillates with the rotation of the transmission shaft.

[0010] The beneficial effects of the utility model are as follows: A seed separating sieve is installed at the front part of the screening device, which can screen the pepper seeds into the seed collecting box. The seed collecting box adopts a vibrating sieve, which can separate small particle impurities, so as to obtain clean pepper seeds, and bring considerable economic benefits to pepper farmers.

[0018] As can be seen in the figures: a feeder 1, a crushing bin 2, a screening device 3, a material lifting device 4, a frame 5, a power machine 6, slats 7, sieve slots 8, a seed separating sieve 9, a seed collecting box 10, a driving idler 11, a driven idler 12, a crank and connecting rod mechanism 13, and a transmission shaft 14. Detailed Embodiments

[0019] The first embodiment: Figures 1 and 2 illustrate a refined pepper screening and picking machine. In order, there are a feeder 1, a crushing bin 2, and a screening device 3. The above-mentioned mechanisms are all installed on a frame 5, and walking wheels are provided under the frame. A power machine 6 is installed at the front part above the frame. Here, the power machine can adopt a diesel engine.

[0020] The so-called feeder, also known as a picker, is provided with a conveyor belt inside. The cut and sun-dried pepper plants are put into the feeder and pushed backward and upward through the conveyor belt and placed into the subsequent crushing bin. After crushing, the stalks are broken into segments, while the peppers after sun-drying have enhanced toughness and are not easily broken, only separated from the stalks. The crushed materials are then put into the subsequent screening device for screening.

[0021] As can be seen in combination with Figure 3, the screening device is cylindrical, and the barrel wall is surrounded by a plurality of long slats 7. The sieve slots 8 between the slats can screen out the crushed stalks, while the peppers are larger in volume and cannot be screened out, and can only flow to the end of the screening device.

[0022] The slats can be made of pipes with a rectangular or trapezoidal cross-section. If trapezoidal cross-section slats are used, the short sides should face inwards. In this way, the gaps inside the sieve slots are larger, which is beneficial for the entry of materials and the screening effect is better.

[0023] Generally speaking, a material lifter 4 and a vehicle are installed behind the screening device. The material lifter is equipped with a lifting belt or a screw auger, or a screw auger can also be installed. After the lifting belt lifts the peppers to a certain height, they can be placed into the carriage. This vehicle can also be used to tow a pepper harvester.

[0024] As can be seen in conjunction with Figure 4, the cylinder of the screening device is placed flat on the frame 5 and supported by the idler rollers on both sides of the frame. One of the idler rollers is the driving idler roller 11, and the other is the driven idler roller 12. The diesel engine drives the driving idler roller 11 on one side of the frame to rotate through a transmission shaft 14, thereby enabling the cylinder to rotate.

[0025] As can be seen in conjunction with Figure 3, the main features of the screening device are as follows: At the front of the screening device, a seed separating sieve 9 is installed. The seed separating sieve is made of a sieve mesh woven from fine wires and is covered with sieve holes through which pepper seeds can pass. Below the frame, a seed collecting box 10 is installed at a position corresponding to the seed separating sieve. The seed collecting box is surrounded by the box walls and the bottom on all sides, and the upper opening of the seed collecting box faces the seed separating sieve.

[0026] During operation, after the materials broken in the crushing bin enter the screening device, the first thing they encounter is the seed separating sieve. The pepper seeds are screened out and fall into the seed collecting box below the frame. Since the sieve holes are very small, the stems and peppers cannot be screened out and can only enter the sieve surface surrounded by the slats backward. The sieve slots here can successively screen out the broken segments of the stems, and the separated peppers pass through the screening device, enter the material lifter 4, and are then sent to the vehicle by the material lifter. When the pepper seeds in the seed collecting box reach a certain quantity, they can be taken out, processed, and packaged for sale.

[0027] The second embodiment: It is improved on the basis of the first embodiment. As shown in Figure 5, the cylinder of the screening device is surrounded by multiple slats, and the cross-section of the slats is triangular, with one sharp angle facing the inside of the cylinder. The gap inside this kind of slat is larger than the gap outside the slat, making it easier for materials to enter and the screening of the stems more thorough. In addition, this kind of slat can also extend to the front end of the screening device to enhance the strength of the seed separating sieve part. Due to the characteristics of the sharp angle, the obstruction to the pepper seeds is very small and will not hinder the screening out of the pepper seeds.

[0028] The third embodiment: The seed collecting box is improved on the basis of the previous embodiment. As can be seen from Figures 6 and 7, the seed collecting box 10 is surrounded by the surrounding box walls and the bottom of the box below, wherein the bottom of the box is provided with a screen, the sieve holes of the screen can retain the pepper seeds and screen out impurities smaller than the pepper seeds. The box wall of the seed collecting box is movably connected to the frame, and it is best to hang it under the frame. A transmission shaft 14 is provided on one side of the frame, and the front end of the transmission shaft is transmitted to the power machine 6. The transmission shaft drives the crank connecting rod mechanism 13 through the sprocket, and the crank connecting rod mechanism is hinged to the box wall of the seed collecting box. Obviously, this seed collecting box is a vibrating screen.

[0029] During operation, when the cylinder of the screener rotates, the vibrating screen will reciprocate left and right, and impurities such as dirt mixed in the pepper seeds will be removed. The remaining pepper seeds are very clean, and subsequent processing is more convenient.

[0030] Experiments have shown that the number of pepper seeds collected during the harvest process is very large, accounting for more than 60% of the pepper seeds sold by pepper farmers during the entire operation cycle, which adds a considerable amount of income to farmers.
